Also can assemble the lighting module 205 of the lamp 206 that comprises predefined type in advance.
Therefore, can treat to form with it the operating position among the device A of one or come assembled components 20 at this assembly according to assembly 20 according to the type and/or the size of described device.Especially, can according to the type of pending particle also/or recently from multiple module, select module 201 and 202 according to technology-economy of being pursued.
Module 201,202 and 205 is put together by the direction shown in arrow F4 and the F5, utilize then any proper device for example bolt these modules are interfixed just can realize this assembly.
Assembly 20 is highly susceptible to making and is easy to and uses, and must adopt regulating system because considering the approaching of breakpoint not resembling in some existed systems.
Preferably with reversible mode Knockdown block 201,202 and 205, thereby they especially can be separated with near lamp 206 during safeguarding.
The structure of assembly 20 also makes its service condition to be optimised, and the temperature of the air by assembly 20 can be 10 ℃ to 60 ℃, and its relative humidity can be 15% to 95%.
Particularly, the organic compound among the air stream F3 is adsorbed by active carbon layer 232.Between layer 232 and 233, there is lasting desorption.Then, the organic compound that in medium 203, does not transform and in this medium 203 intermediate compound of part redox gained processed in medium 204.
By mineralization, assembly 20 can destroy the organic pollution in the air stream fully.
Particularly, the present invention can handle the air stream that comprises VOC (VOC) or half volatile organic compound, perchloroethylene, 2-butylene, methyl phenyl ethers anisole, phenol, ozone, chloramines, lindane and/or its mixture.The present invention can also handle the compound air stream of mercaptan or cigarette smoke for example that comprises generation (smelly) smell.The present invention can also handle the air stream that comprises potential pathogenic viable microbial, and described pathogenic viable microbial is bacterium or virus for example, and described bacterium is veteran bacterium or staphylococcus for example, and described virus is SARS virus for example.
According to unshowned modification of the present invention, device A can be designed so that filter 20 is in the downstream of blower fan 22.
Utilized integral component 20 that the present invention has been described.Yet also available separated components forms described assembly.
